J599 Series III Circular Connectors (38999 Series III Type)
38999 Series III type · shell sizes 9–25 · 184 insert arrangements



Panel flange + PCB flange · 17 mm spacing · 50 PCB layouts
Double-flange receptacles mount to the equipment panel and to the circuit board at the same time, so the board carries no connector loads. They are available in the bayonet Series I style (JY27505E-D17) and the threaded Series III style (J599/20-D17 and J599/20-E17), with PCB pin or socket contacts and marine-grade versions.

The panel flange takes the mating and cable loads, and the second flange fixes the connector to the circuit board, so the solder joints carry no mechanical stress.
Yes. We supply hole coordinates for each layout, for pin and socket versions. Recommended hole diameters are Ø 0.90 mm for sizes 22D and 20 and Ø 1.30 mm for size 16.
The standard spacing is 17 mm. Tell us your panel-to-board distance and we will review a custom spacing.
